AIC1722-33CX中文资料沛亨半导体数据手册PDF规格书

■ DESCRIPTION

The AIC1722 is a 3-pin low dropout linear regulator. The superior characteristics of the AIC1722 include zero base current loss, very low dropout voltage, and 2 accuracy output voltage. Typical ground current remains approximately 55µA, from no load to maximum loading conditions. Dropout voltage at 100mA output current is exceptionally low: 130mV for the AIC1722-50 and AIC1722-52, 180mV for the AIC1722-33, AIC1722-35, and AIC1722-37 AIC1722-38. Output current limiting and thermal limiting are built in to provide maximal protection to the AIC1722 against fault conditions.

The AIC1722 comes in the popular 3-pin SOT-89 and TO-92 packages.
